A British judge said a woman, who was desperate for another child forced her 14-year-old daughter to get pregnant, using syringes of donor sperm.
High Court judge Peter Jackson said the mother had behaved in "a wicked and selfish way" that almost defied belief.
The judge said the woman, an American living in Britain with three adopted children, hatched the plan after she was prevented from adopting a fourth.
The plan involved attempting to inseminate her eldest daughter with syringes of sperm purchased over the Internet.
An initial pregnancy ended in miscarriage, but the daughter gave birth to a baby boy from donor sperm when she was 17.
Details of the case were reported for the first time Monday after the media challenged reporting restrictions at family court.
